Is planetary chaos related to evolutionary (phenotypic) rates?

TL;DR

This paper explores a potential link between planetary chaos, characterized by Lyapunov time, and biological evolutionary rates, proposing an inequality that aligns with observed data in biological evolution.

Contribution

It introduces a novel inequality connecting planetary chaos timescales with phenotypic evolution rates, supported by empirical biological data.

Findings

Lyapunov time and evolutionary rate are closely related numerically.

The proposed inequality fits well with known biological evolution cases.

Suggests a possible fundamental link between planetary dynamics and biological evolution.

Abstract

After Laskar, the Lyapunov time in the solar system is about five millions years (5.000.000 [years]). On the other hand, after Kimura, the evolutionary (phenotypic) rate, for hominids, is 1/5.000.000 [1/years]. Why are these two quantities so closely related? In this work, following a proposition by Finlayson and Hutchings et al, I found an inequality, which relates Lyapunov time and evolution rate. This inequality fits well with some known cases in biological evolution.
